Answer:
Answer:
Cost of one (chicken) = $
8
Cost of one (duck) =
$
5
Explanation: heyy there :)
Let c be (chickens) and d be (ducks)
Given :
50
�+
30
�
=
$
550
Dividing both sides by 10,
5 + 3 = 55 Eqn (1)
44 + 36 = $ 532
11 + 9 = 133 Eqn (2)
Multiply Eqn (1) by 3 to eliminate y term when subtraing Eqn (1) from (2).
Then a Eqn (1) becomes, 15 + 9 = 165 Eqn (3)
Subtracting Eqn (2) from (3),
(15 - 11) = (165 - 133)
4 = 32 or = $ 8.
Substituting value of in Eqn (1),
(5 * 8) + 3 = 55
3 = 55 - 40 = 15
= 15 / 3 = $ 5
